To all whom it may concern j Be it known that I, J BIROHARD GR EN, acitizen of the United States of America, and resident of Chicago,Illinois, have invented a certain new and useful Improvement in Reels,of which the following is a specification.

The invention relates to reels for wire for use, for example, onstapling machines, or other machines requiring the feeding of Wire fromcoils;

Generally stated, the object of the invention is to provide a novel andimproved reel of this kind which can be manufactured at a comparativelylow cost of production andwhich; will be durable and satisfactoryin use.v

A special object is to provide an improved construction and arrangementwhich will obviate thenecessity of using a tube in the reel, but whichwill result in a reel adapted to be easily adjusted into place onaspindle, and which can be readily removed and taken apart to receive afreshcoil of wire.

Another objectis to provide an improved formation of the inner sides ofthe flanges of the reel to facilitate the removal of the I bindin sfromthe coil of wire.

.To t eseand other useful ends the "inven- .t'ion consists in mattershereinafter set forth and claimed, and shown in the accompany'-" indrawings, in which-.- r

igure 1 is a vertical and axial section on line 11 in Fig. 2. f

Fig. 2 is a side elevation of the reel shown in Fig. 1. A

As thus illustrated, the invention com-' prises a fixed flange 1 havinga tapered hub 2, this hub being internally threaded at 3 in the outer orsmaller end portion thereof, and the larger end of the hub beingintegral with the flange. The removable flange 4 has a central boss 5 onits inner side, said boss being threaded to screw into the threadedportion ofthe hub. The flange 1 is provlded with a central hole 6, andthe boss-5 is provided with a central bore 7 in alinement with saidhole. It will also be seen that the hub $2, is hollow to provide achamber 8 therein,

so that the spindle is thereby inserted through the reel. I

As a matter of further and special im provement, the flange 1 isprovided with radial grooves 11 on its inner side, these grooves"StOPPIIIg short of the outer edge of the flange at them outer ends, andterminatingat their inner ends adjacent the larger end of the taperedhub. The flange 4 has its inner "side provided with similar radialgrooves 12, but these grooves are longer thanthe grooves 11 as theyterminate at the smaller end "of the tapered hub. For example, theseradial "grooves may be sixin number on 'each' flange, but they can beofany suitable or desired'number. When the-coil of wire 13 is slipped onto the tapered hub 2, after the removal of the flange 4:,the bindings ofthe coil, which ordinaril are short pieces of wire wrapped around t ecoil, can

then be adjusted in place in the grooves 11 and 12, and with the coilthus held in place the bindings can then be removed and pulled out ofsaid grooves; Thereafter, if necessary, the flange4 can be screwed uptight until its shoulder 14c bears against the smaller end ofthetaperedhub, and in this position the removable flange is held againstunscrewing by its frictional engagement with thehub. p

With this construction the screw threads for connecting the removableflange to the tapered hub can be smaller than in other constructions,but being of considerable diameter, will afford greater, or at leastsuflicient, friction to keep the flange from being unscrewed while thecoil of wire is being unwound. In otherwords, the screw threads forconnecting the. tapered hub to the boss on the removable flange can beof smaller or finer pitch than in other constructions, bea. cause of theincreased 'dlameter .of the threaded portions, and while these finerthreads are of less depth," the increased diameter increases the lengthof thread cir- .cumferentially to an extent that the tend- "is madepossible, thereby materially reducing the weight of the reel, which alsofacilitates the unreeling of the wire. It will be seen, therefore, thatthe construction as a standing the use of soft metal, such as wholetends to reduce the weight of the reel, but at the same time has theadvantage of facilitating the removal of the binding wires from thecoil; and, in addition, notwithaluminum, the screw-threads are notliable to become stripped, as the diameter of the threaded parts isgreater than heretofore and with screw threads of a smaller'orfinerpitch, as explained, the user can very easily screw the removable flangeinto the'tapered hub and without very much effort .w tightly compressthe coil to produce the dc-o sired results.

While the grooves shown for facilitating the removal of the bindingwires from the coil are straight, it. will be understood that thesegrooves, which arelrecesses, may be of any suitable or desired shape.

he recesses 11 terminate at the maximum diameter, of the tapered hub: 2,while the relatively large recesses 12 terminate at the minimum diameterof said hub. The screw threaded connection, when operated by relativerotation of the twoflan'ges, causes the two flanges to move toward each"other, so that the portions between the recesses are brought intoengagement with the sides of the eoil of wire. The recessed inner facesof the two flanges are, it will be seen, disposed in parallel planes,sothat these recessed faces having a tapered hub, which hub is internallythreaded atits smaller end, the flange being integral with the largerend of the hub and provided with a central hole, a removable flangehaving an externally threaded boss to screw into said threaded end ofthe hub and formed with a central bore in alinement with said hole, sothat the entire spool thus formed comprises only two screw connectedparts, each part including an integralflange, and the two flanges beingspaced apart to hold a coil of wire between them,

in combination with a spindle extending throu h said hole and bore.

3. A reel for wire, comprising a hub to hold the coil of wire, flangesto maintain the coil on the hub, said flanges having their flat innersides provided with recesses, means to support the hub and flanges forrotation, V

and means to clamp and compress the coilof wire between the recessedfaces of the flanges;

the removable flange having relatively long recesses on the inner facethereof, so that some of said recesses terminate at'the'maxi mumdiameter of the hub while the other recesses terminate at'the minimumdiameter of the hub.

In a reel for wire, the combination of a hollow hiib, a non-removableflange fixed thereon at one end thereof, so that the other end of thehub is left open, and a removable flange provided with a screw threadedboss adapted to befscrewed into the open end of saidhub, both flangesbeing apertured at the axial center of the spool like structure thusprovided, so that an axis member may extend through said hub to supportthe reel for rotation, and said boss being non-removably fixed on saidremovable flange.
